Cambodia and Thailand agreed on Thursday to invite monitors from the Association of Southeast Asian Nations to oversee a fragile ceasefire along their 817-kilometre border, formalising a truce that halted the worst fighting between the neighbours in more than a decade. During an extraordinary session of the bilateral General Border Committee at Malaysia’s armed-forces headquarters in Kuala Lumpur, Cambodian Defence Minister Gen. Tea Seiha and Thai acting defence chief Gen. Nattaphon Narkphanit signed a joint statement committing both armies to cease all weapons fire, avoid unprovoked engagements and refrain from reinforcing troops or equipment near contested areas. Under the accord, an observation mission composed of ASEAN military attachés—co-ordinated by Malaysia—will be stationed on both sides of the frontier to report on compliance. Regional army commanders are scheduled to reconvene in two weeks, with the full committee to meet again within a month to review progress and discuss longer-term border demarcation. The five-day clash in late July claimed at least 43 lives and displaced more than 300,000 people before a U.S.-brokered halt to hostilities took effect on 29 July. China hailed Thursday’s agreement as a step toward lasting stability, while Phnom Penh said it has nominated U.S. President Donald Trump for the Nobel Peace Prize, citing his threat to suspend trade talks unless the ceasefire held.
